What is the difference between a psychologist, psychiatrist, and counselor?

These three professions serve the mental health field but operate under different training frameworks and legal authorities. A psychiatrist is a medical doctor (MD or DO) who completed medical school and a residency in psychiatry. Because they are physicians, psychiatrists can prescribe medications, order medical tests, and diagnose mental health conditions from a medical perspective. Their work often focuses on the biological aspects of mental illness and medication management.

Psychologists typically hold a doctoral degree (PhD, PsyD, or EdD) in psychology and complete postdoctoral supervised practice. They are trained in psychological assessment, testing, and evidence-based therapeutic techniques. Psychologists cannot prescribe medication in most states, though they conduct in-depth psychological evaluations and provide talk therapy. Their training emphasizes research, behavior analysis, and cognitive functioning.

Counselors (also called licensed professional counselors or LPCs) usually hold a master's degree in counseling or a related field and complete supervised clinical hours. Counselors provide talk therapy focused on life challenges, mental health conditions, and personal development. Like psychologists, counselors typically cannot prescribe medication and emphasize therapeutic relationship and coping skills.

In Columbia, many people seek out mental health counseling services based on whether they need medication management (psychiatrist), psychological testing and assessment (psychologist), or therapy focused on life and emotional issues (counselor). Each role has distinct value depending on your needs.
